| pubmed-article:6974527 | pubmed:abstractText | A study of a small Y chromosome, found in a family line established in Canada since 1664, and traced back in France in some descendants of a sixteenth century ancestor related to the canadian one, has shown, by C-, G- and Q-banding techniques, that it was deleted of the q12 segment. This study suggests that the del(Y)(q12) results from the oldest known chromosome aberration. | lld:pubmed |
